Book 28 on drugs from the Al-Tasrif, a 30-volume Arabic encyclopaedia on medicine and surgery, written ca. 1000 CE by Abulcasis.  ISTC No. ia00014000. Digital facsimile from the Württembergische Landesbibliothek Stuttgart at this link.

The surgical section of Albucasis’s Altasrif, the first rational, complete and illustrated treatise on surgery and surgical instruments. The author was an  Arab Muslim physician and surgeon who lived in Al-Andalus. During the Middle Ages this was the leading textbook on surgery until it was superseded by Saliceto. The work was first published in print in the Latin translation by Gerard of Cremona, in this collective edition, in which Guy de Chauliac's surgery was the lead title. Besides its significance in general surgery and for the history of surgical instruments, Albucasis's work was “of great importance for the development of practical dentistry” (Hoffmann-Axthelm). Chapter 28 discusses excision of epulis. Chapter 29 deals with calculus. Albucasis understood that calculus on the teeth is a major cause of periodontal disease and gave explicit instructions for scaling the teeth, describing the instruments which he invented for this purpose. Chapter 30 covers tooth extraction, and Chapter 33 contains one of the earliest discussions of tooth prostheses, and describes some oral surgery procedures. The work contains some of the earliest illustrations of dental instruments. See No. 5550.  

Note that Albucasis's surgery, a work of significant practical value, was the last, or one of the last, of the medieval classics of surgery to be printed. ISTC no. ig00564000. Digital facsimile from the Bayerische Staatsbibliothek at this link.  

A superbly illustrated 14th century MS of Albucasis was reproduced in full color facsimile as Codex Vindobonensis Series Nova 2641, Graz, Akademische Druck, 1979.

This is the first printing of the medical and therapeutic section of Abul Qasim’s medical encyclopedia or al-Tasrif. It contains what is probably the earliest description of hemophilia (fol. 145). Digital facsimile from Google Books at this link.

In this, the first printed edition of Rerum medicarum libri quatuor by the late antique Byzantine physician Theodorus Priscianus, his work was misattributed to Octavianus Horatianus. Digital facsimile from Google Books at this link. It may be somewhat ironic that Priscianus's work, of relatively limited value from a period in which there was little or no medical advance, was published together with Albucasis' surgery, a work of the greatest practical value.

"Priscianus was a pupil of the physician Vindicianus, fixing the period of his life in the fourth century. He is said to have lived at the court of Constantinople, and to have obtained the dignity of Archiater. He belonged to the medical sect of the Empirici, but not without a certain mixture of the doctrines of the Methodici, and even of the Dogmatici^{[1][2]" (Wikipedia).}

This parallel Arabic-Latin edition prepared by the apothecary John Channing is the first printed edition in Arabic, and the first modern edition of the text. Digital facsimile of the 1778 edition from Bayerische Staatsbibliothek at this link.
